Before I heard of the AE Modulard format, I was about to start DIY and wanted to do the simpliest oscillator and sequencer. Unfortunalty for me, I don't know anything about electronic and I bearly can read a schematic, but I bet it's not hard to learn. I've gatherd some potentiometers, wires, breadboard and some component and I think I'm ready to get started. But, as there is always a but, I have some question at first. I planned on making a few sequencers, just to have fun and learning DIY, but I'm searching for something very basic as I'm just getting started. I don't neet to make the sequencer the same size of the AEM as I have plenty of space for boxes and such.
- The AEM run on 5V, how can I make a sequencer sending 5V?
- Is there any simple, basic, rudimentary schematic to make a sequencer with a 4017IC that can be suitable for the AEM?

yes, this is really easy - and one of the first DIY projects I did with the AE modular. you can see it here, at about half way thru I used the OMSynth board, but you can do it on a plain breadboard, it was based on an OMsynth project as a basis which you can just copy. details are here, with schematics: bastl-instruments.com/support/tutorials/omsynth-project-2and even a video where Peter (casper electronics, now bastl) walks you thru it its very simple the CD4040 is just a counter which moves thru the steps this drives a CD4051 multiplexer, which simply selects which pot is used for the output voltage. thats it! note: the circuit shows a CD40106 to drive it, and be a sound source, but you'll just use a clock/lfo and oscillator from the AE modular... also its fine to run this all off 5v (not 9v as shown in video) the second CD4051, is just used to drive the LEDs so you can see which step is active, and learn an important lesson ... multiplexers are bi-directional. if you want to also have gates, thats trivial too... just add another CD4051, and rather than pots use (non momentary) switches. then from here is you can have some fun extending it... eg. messing with the counter chip to reset it... ( I think Peter also mentions some other tricks you can do in his video... actually watch his series, I found it quite inspirational) |
